Which is something that is much more likely to stick with you, yes.

There is always an event flow even if the propagation path contains only
a single EventTarget. Besides, there certainly are other hierachial ob-
jects that are EventTargets but not Nodes, like SVGElementInstances or
various objects in Adobe Flash et al., or entirely custom objects like
you can make them with the implementation in Google's Closure Library.

You'd have a point if nobody ever wondered how the XHR event flow works,
but this isn't the first time questions about that have ended up here.
